After reconnect the leader to network, we tick it to resend
previous data. However, if it's ticked too excessively, it
may step down to follower due to `CheckQuorum` being enabled.
This causes the test to fail.

Instead of ticking it, this CR changes one test to simply
enque one more tx to trigger resend of previous data.
